Context: Haller cells are extensions of ethmoid cells which can be seen in several imaging modalities. Literature search has shown that idiopathic orofacial pain is associated with the presence of Haller cells. Hence, a simple cost-effective imaging modality for displaying the presence of Haller cells is desirable. Aims: This study aims to determine the prevalence of Haller cells in panoramic radiography. Subjects and Methods: The retrospective study comprised of 403 individuals of both genders. Panoramic radiograph was taken for every individual and interpreted for the presence of Haller cells. Factors incorporated in the interpretation were prevalence of Haller cells, distribution of Haller cells among genders, site predilection, unilocular or multilocular variant, and most common shape prevalent among the individuals. Statistical Analysis Used: Chi-square test with SPSS software. Results: Among 403 individuals, the Haller cells were present in 92 (22.8%) individuals. Of 92 (22.8%) individuals with Haller cells, 40 (18.5%) were males and 52 (27.8%) were females. Seventy-four individuals (80.4%) were unilocular and 18 (19.6%) were multilocular. Forty-five individuals had (48.9%) tear-shaped Haller cells, 27 (29.3%) had round-shaped Haller cells, and 20 (21.8%) had oval-shaped Haller cells. Forty (43.5%) were on the right side, 29 (31.5%) were on the left side, and 23 (25%) were on both sides. Conclusions: The present study assessed the prevalence of Haller cells as 22.8%, and this was done in a cost-effective way using panoramic radiographs.
